Araldite® is an epoxy resin commonly used for embedding. It is basically free from polymerization damage and the plastic does not sublime in the microscope, hence providing continual support and preservation of fine detail.[1] It is composed of araldite M or CY 212, dodecenyl succinic anhydride, dibutyl phthalate and 2,4,6-tridimethylamine methyl phenol.

Spurr resin is a hydrophobic resin. It is less viscous than epon mixtures and is easier to dispense. The low viscosity of the resin contributes to its penetration in tissue, mineral and dense structures. A low viscosity of 60 cps also allows easy penetration into a variety of difficult materials.

PolyFreeze is a water-soluble support matrix and a form of embedding medium for frozen sectioning. PolyFreeze sections flawlessly at routine frozen specimen thickness of 5-6 μ and leaves no slide residue. It provides for -20 ºC cryostat sectioning in rapid set embedment. This medium freezes quickly supporting the tissue for sectioning at 3 mm and up with no cracking of the matrix at temperatures from -8 °C to -25 °C.

The Epoxy Embedding Medium Kit is a very widely used embedding medium for electron microscopy. The embedding formulation originally published by Luft (1961) is excellent for both plant and animal tissues. Due to the low viscosity of the resin, it penetrates the tissue specimen faster than Araldite and other polymers. It hardens easily and uniformly at low temperatures with the addition of dodecenylsuccinic anhydride (DDSA), methyl nadic anhydride (MNA), and the accelerator 2,4,6-tris(dimethylaminomethyl)phenol (DMP-30). Slight shrinkage may occur during curing. This kit is useful for embedding a variety of tissues as a wide range of hardness can be obtained with this resin to suit a specific tissue type by using two different anhydride curing agents (DDSA and MNA).

A range of mounting media for manual and automatic mounting of slides. The Q Path® Coverquick range consists of four different mounting media with different viscosities to meet all microscopy needs. The number after the name indicates increasing viscosity: Q Path® Coverquick 1000 has the lower viscosity (around 260 mPaS) and Q Path® Coverquick 4000 has the higher viscosity (around 920 mPaS).

Entellan® new is a new mounting medium for cover slippers and is specially suited for commercial automated mounting instruments that operate with cover slippers. Its viscosity ranges between 250 and 600 mPas, 1,00869 has a small viscosity range. This narrow viscosity range improves and accelerates the application, as neither the dropping rate nor the volume need to be reset after the first run with a new bottle of Entellan® new.

CC/mount is an aqueous based permanent mounting medium with a very high refractive index, which when applied to the stained tissue sections can store the tissue specimens permanently without the fading of the chromogens. Because of the superior refractive index of CC/mount, tissues mounted in this medium look like specimens mounted with organic based mounting media. No coverslipping is required with CC/mount. However, if coverslipping is required, dried CC/mount can be post mounted by using an organic based mounting medium. CC/mount permits the long-term storage of antigens localised using organic insoluble chromogen substrates, including AEC, DAB, Fast Red, BCIP/NBT, BCIP/INT and fluorescent dyes like FITC and phycobiliproteins. The high pH of CC/mount ensures increased stability of fluorescence intensity.

When sectioning frozen tissue for rapid surgical biopsy diagnosis or for research (typically in Histochemistry), the tissue sample must be firmly attached to the microtome stage or chuck. Embedding material such as OCT are preferred as these also provide a supportive and protective aid to sectioning.
